G001 — transition=[from,input-or-null,to]且允許empty alphabet/final set的finite epsilon-NFA。操作=nfa-accepting-path-witness；資料={"states":["s24","m24","f24","d24"],"alphabet":["a24","b24"],"start_state":"s24","final_states":["f24"],"transitions":[["s24",null,"m24"],["s24",null,"d24"],["m24","a24","m24"],["m24","b24","f24"]],"input":["b24"],"path":[["s24",0],["m24",0],["f24",1]]}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。

操作後
explicit ordered source output fields=[input, path, transition_indices, valid_path, accepted, certificate]

操作後
states nonempty with actual start;alphabet/final set/relation MAY be EMPTY;definition qualification does NOT prove determinism,totality,DFA equivalence or a successful run
條件：無
空final set合法且辨識空語言；空alphabet也合法。定義合格不保存在accepting path，亦不推deterministic或DFA等價。

操作後

條件：無
先核整條path的state／position資格與真initial；合法config列表不保相鄰transition存在。

按原transition索引取首個真匹配者，包括duplicate edges；null增0，symbol增1且必讀到原input。失敗保partial prior indices，不用後面final state補錯步。

valid_path=是;FULL input consumed=是;last final=是;accepted=是;one successful finite path suffices despite dead branches
條件：無
valid與accepted分開，premature final不接受。accepted=True才是這個word的有限存在見證，不推機器deterministic、total或DFA等價；tag不把False變True。
